When you are caring for someone who is ill, elderly, or disabled, it's important to consider how you'll handle those times when you can't be with your loved one in person. Thankfully, today's technology offers options that can help you keep track of your loved one's safety and well-being.

Most people are familiar with the emergency response system known as Lifeline. Experts call devices and systems like Lifeline "telecare." But there's much more to telecare than emergency assistance. Today, there are a multitude of telecare devices that can help you stay informed of your loved one's activities and needs in real time.

Caring for an aging parent or a loved one who is ill or disabled is often deeply rewarding. But it can also consume a lot of time, as well as physical and emotional energy. You may feel overwhelmed by myriad responsibilities — home, work, other family needs, and caregiving. But it's just as important to care for yourself before you burn out. Try our five tips below to help rejuvenate yourself.

1. Recruit help: You don't have to "do it all" yourself. In fact, it's best to have more than one person involved in caregiving. Whether it's accompanying your loved one to appointments, helping with housework, or cooking dinner one night a week, ask other family members to lend a hand. And if someone asks if he or she can pitch in, don't be afraid to say yes!

You're probably already doing a lot to ensure that you stay in good health and are able to enjoy your later years: eating right, exercising, getting checkups and screenings as recommended by your doctor. But it also makes sense to have some contingency plans for the bumps in the road that might occur.

1. Adapt your home. Stairs, baths, and kitchens can present hazards for older people. Even if you don't need to make changes now, do an annual safety review so you can make necessary updates if your needs change.
2. Prevent falls. Falls are a big deal for older people — they often result in fractures that can lead to disability, further health problems, or even death. Safety precautions are important, but so are exercises that can improve balance and strength.
3. Consider your housing options. You might consider investigating naturally occurring retirement communities (NORCs). These neighborhoods and housing complexes aren't developed specifically to serve seniors — and, in fact, tend to host a mix of ages — but because they have plenty of coordinated care and support available, they are senior-friendly.
4. Think ahead about how to get the help you may need. Meal preparation, transportation, home repair, housecleaning, and help with financial tasks such as paying bills might be hired out if you can afford it, or shared among friends and family. Elder services offered in your community might be another option.
5. Plan for emergencies. Who would you call in an emergency? Is there someone who can check in on you regularly? What would you do if you fell and couldn't reach the phone? Keep emergency numbers near each phone or on speed dial. Carry a cellphone (preferably with large buttons and a bright screen), or consider investing in some type of personal alarm system.
6. Write advance care directives. Advance care directives, such as a living will, durable power of attorney for health care, and health care proxy, allow you to explain the type of medical care you want if you're too sick, confused, or injured to voice your wishes. Every adult should have these documents.

Women are at greater risk for dementia. Joining clinical trials can help to speed the development of promising drugs.

Being a caregiver for an ailing parent, spouse, child, or other loved one can feel like a lonely undertaking. It needn't, even if you don't have family nearby to pitch in. Help for caregivers is available from various organizations. Once you learn what's available, it may be easier to chart a less-demanding course toward meeting the needs of your spouse, relative, or friend.

Here are some types of services and professionals you might want to investigate.

Researchers from the biotechnology company Biogen have reported that a new drug reduced the amount of amyloid plaques—the brain deposits associated with dementia—and slowed cognitive decline in people with early Alzheimer's disease. They presented the report March 20, 2015, at the International Conference on Alzheimer's and Parkinson's Diseases in Nice, France.

The researchers studied 166 people ages 50 to 90 who had been diagnosed with mild Alzheimer's. The participants were randomly assigned to receive either a placebo or one of four different doses of the drug aducanumab—an antibody that attaches to amyloid deposits and turns the immune system on them.

One of the most dangerous and distressing symptoms of Alzheimer's is wandering. It may seem unfathomable that a person might suddenly get up at night to go to the post office or leave home at any hour for no apparent reason. But wandering may be prompted by deep-seated memories of work, chores, or hobbies, or a longing to return to a former home.

The inability to control wandering is what often drives families to decide to place a loved one in a nursing home. However, there are some simple measures to prevent wandering that often work well for a time and can even help postpone that difficult decision.

Over time, most people with dementia or mild cognitive impairment (a decline in thinking skills) also experience behavioral changes, such as depression and agitation. Which comes first? A study published online by Neurology on Jan. 14, 2015, suggests that psychological and behavioral changes can begin before people develop mild cognitive impairment or dementia. Researchers evaluated the daily functioning, memory and thinking skills, and psychological and behavioral symptoms of about 2,400 people, ages 50 and older, who had no evidence of cognitive decline. The study also suggests that a pattern of depressive symptoms may occur in older adults, unrelated to cognitive decline. The takeaway? "Depressive symptoms can occur in older adults for many reasons. If you are experiencing mood or cognitive changes that last for more than a few weeks, it's a good idea to bring this up with your doctor or consult a mental health specialist to help sort out possible causes," says Dr. Nancy Donovan, an instructor in psychiatry at Harvard Medical School. 

Anticholinergics, a group of medications that includes many over-the-counter and prescription drugs, are well known for causing confusion in older adults. Common medications with anticholinergic properties include medications to treat overactive bladder, such as oxybutynin (Ditropan); medications to treat allergies and sleeping problems, such as diphenhydramine (Benadryl, Sominex, Unisom); and medications used to treat depression, such as amitriptyline (Elavil). It's generally believed that confusion that may develop from anticholinergics clears up when someone stops taking the drugs. But now it appears that the medications are associated with a more permanent effect. A study published online Jan. 26, 2015, in JAMA Internal Medicine linked daily anticholinergic use among older adults for three or more years to an increased risk for developing dementia and Alzheimer's disease.

The study didn't prove that anticholinergics cause dementia; it only found an association between people who take the medications and people who develop dementia. Nevertheless, the researchers suggest that doctors avoid prescribing anticholinergics when possible, or at least limiting the medications to the lowest doses possible. If you're taking an anticholinergic, talk to your doctor about the risks the medication poses, including the risk of falls as a result of confusion.

At middle age, the brain begins to draw on more of its capacity for improved judgment and decision making.

If you forget a name or two, take longer to finish the crossword, or find it hard to manage two tasks at once, you're not on the road to dementia. What you're experiencing is your brain changing the way it works as you get older. And in many ways it's actually working better. Studies have shown that older people have better judgment, are better at making rational decisions, and are better able to screen out negativity than their juniors are.
